Flat Belt Conveyors

Flat belt conveyors are a great way to streamline your production process. They are easy to maintain and can help you save money on cleaning costs. They are also safe for your workers.

One of the most important aspects of a flat belt conveyor is its take-up system. This takes up slack in the conveyor belt and helps keep it at optimum tension.

Troughing idlers

Troughing idlers, also called troughers or carriers, are a type of belt conveyor idler that helps to reduce material spillage and improve conveyor performance. They are typically constructed from a central roller with wing rollers connected in a troughing angle, which enables them to better distribute the load weight across the belt. This allows the conveyor to carry greater tonnages per hour and saves on belting costs. The rollers are often fabricated from electric resistance welded steel mechanical tubing and coated with a wear-resistant rubber lagging or a high molecular weight polyethylene sleeve. These materials can withstand harsh conditions such as abrasive or corrosive material and provide longer belt conveyor idler life than standard steel roll idlers.

The troughing idler is used on both Uni-directional and Bi-directional flat belt conveyors. Its tapered wing rollers allow it to track the belt even when it moves off-center. This prevents the belt edges from making contact with stationary parts of the conveyor structure and prevents abrasion, which can lead to belt damage and reduced capacity. The wing rollers can also reduce the amount of wet or sticky material that accumulates on the return side of the conveyor.

The troughing idler is available in two-roll, three-roll, and five-roll units. Its design and mounting bracket allow the unit to accommodate both abrasive and non-abrasive Flat belt conveyor material. It is important to limit the sag of the troughed idlers during normal operation. Too much sag can cause the belt to slip off the idlers and cause the conveyor to lose efficiency.

Wing idlers

The design of conveyor belt idlers plays a key role in determining the performance of a conveyor. For example, the spacing of idlers affects how well they support and shape the belt. Too much space between the idlers will reduce their effectiveness. Similarly, too little space between the idlers will cause the belt to deviate from its center line. This can lead to premature wear and damage to the belt. In addition, it can increase the weight and cost of the belt. A solution is to use tapered wing idler rollers to ensure that the roller activates immediately as the belt moves off-center. This will ensure that the idlers do not make contact with the conveyor structure, saving the belt from unnecessary wear and tear.

The spacing of conveyor belt idlers can be adjusted to create different types of troughing patterns. The most common type of troughing idlers is the three-roll carrying idler. This configuration consists of two outer rolls that are inclined upward, and a central roll that is horizontal. This arrangement provides a greater cross-sectional fill depth than flat belts with the same width. It also increases the load-bearing capacity of the conveyor system.

Another option for troughing idlers is the two-roll “Vee” return idler. It offers some training effect, and it allows for larger idler spacing. However, it can cause abrasion and material build-up on the shell of the rollers, reducing their life. Therefore, the spacing should be carefully calculated to prevent this problem.

Snub pulleys

The snub pulley works in conjunction with the head pulley and is used to enlarge the contact area between the belt and the drive pulley. Flat Belt Conveyor Manufacturer This allows the belt to gain more traction and makes it ideal for systems that require high drive power or conveyors in contaminated environments. Spiral, heavy duty, and herringbone wing idlers are all common types of snub pulleys.

In installations with a strong run-off tendency and considerable transverse forces (side loading, diverting), cylindrical-conical pulleys are not enough to keep the belt properly tracked. In such cases, a number of other tracking measures may be required to correct the situation. Guiding profiles are well suited to this purpose and are usually V-shaped. They are welded or glued onto the running side of the belt and can be found in rectangular and semicircular versions as well.

Another common tracking measure is inclined rollers on the return side of the conveyor. These can be a great solution for wide, short belts that are operating at high speeds. They also work well for reducing the lateral force applied to the tail pulley and can help to prevent spillage of material. However, it is important to note that inclined rollers can cause a lot of wear on the conveyor belt and must be kept clean. For this reason, they are best used in transfer and load points.

Tail pulleys

Flat belt conveyors are often used in agriculture equipment, like threshing machines and silo blowers. They can also be found in industrial applications, including cooling, draining, and heating. They can be used to transport a wide variety of materials, from grain and wood to liquids. These systems can be operated manually or automatically, depending on the application.

The belts of a Flat belt conveyor are typically constructed with a rubber or ceramic lagging material. The head pulley, which is located at the conveyor discharge point, is usually lagged as well. The tail pulley is typically the wing type, which helps the conveyor clean the belt and reduce the risk of lumps of material sticking between the rollers.

The tail pulley can be fitted with a range of wings, such as herringbone, spiral, or chevron. The wing types help prevent dirt from damaging the belt and can be installed on both sides of the pulley. The wing type of tail pulley also helps to reduce the risk of entrapment between the belt and pulley, which could cause abrasions or holes in the belt.

A cleated tail pulley is a great way to improve the traction of the belt during inclines or declines. The cleats help to separate equal segments of the belt, which help resist leverage forces. The cleated tail pulley can be found in a number of industries, from processing to assembly lines.
